This makes Brexit take a back seat: hints of ancient life have appeared on Mars. Carbon building blocks and other signs of past microbes are thought to lie in Jezero, a 28-mile-wide crater just north of Mars’s equator. The crater was once filled with a lake that was 800ft deep. Just imagine the sailing that went on among upper-class Martians 3.5 billion years ago. It was warmer back then — up there, that is — and that lake, I am certain, was where the elite met to eat and swim. And sail.
We humans have been evolving for some time now, but not really. Only a few decades ago we were certain that the oldest human fossil was a small-brained female by the name of Lucy. Lucy was known as Australopithecus afarensis, and she existed between 3.85 and 2.95 million years ago. Human evolution, it is believed, followed a direct path from Lucy to modern woman.
